Characterization of protein crosslinking to the surface of the gel. a Principle of the measurement. The AFM tip is brought close to the gel until a contact is made between the anti-collagen antibody on the tip and the protein at the surface of the gel. Then the tip is retracted until the contact breaks at the values noted as Ladh and Fadh. b Boxplot of the adhesion forces between the anti-collagen I antibody and the collagen I presented on the networked or the linear PAA. c Boxplot of the adhesion length between the anti-collagen I antibody and the collagen I presented on the networked or the linear PAA. *Statistically significant difference with a p-value of <0.01, as calculated by non-parametric Tukey's tests
